how can I send coordinates to parse and save it as

问题:

How can i send coordinates to Parse fetched by CLLocation and save it there as PFGeoPoint's latitude and longitude?

I am able to get the coordinates from CLLocation and I want to send it to Parse. In Parse I have a column named "coordinates" of type PFGeoPoint which has two fields.Now I want to save the coordinates which I have got from CLLocation to Parse Column coordinates. can anyone please help me with this? I am new to iOS and Parse.

Two steps:

1. Convert CLLocation to PFGeoPoint

   //SWIFT
   let point = PFGeoPoint(location: currentLoc)
   
   //Obj-c
   [PFGeoPoint *point = PFGeoPoint geoPointWithLocation:(PF_NULLABLE CLLocation *)location];
   

2. Now save it.

   //SWIFT
   object["coordinates"] = point
   object.saveInBackgroundWithBlock {
     (success: Bool, error: NSError?) -> Void in
     if (success) {
               // The object has been saved.
     } else {
               // There was a problem, check error.description
     }
   }
   
   //Obj-c
   object["coordinates"] = point;
   [object saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
     if (succeeded) {
       // The object has been saved.
     } else {
       // There was a problem, check error.description
     }
   }];
